Sources: All FY2025 and FY2024 figures are company-disclosed GAAP results from Aon plc's 'Aon Reports Fourth-Quarter and Full-Year 2025 Results' press release (issued Jan 30, 2026, filed as Exhibit 99.1 to Form 8-K, sec.gov/Archives/edgar/data/315293/000162828026004273/ex991prq42025.htm) and Aon plc's Form 10-K for FY2025 (filed with the SEC Feb 13, 2026; ir.aon.com/image/Aon+plc+2025+10-K-2026-02-13-14-54.pdf). Aon reports two solution lines, Risk Capital and Human Capital, following its 2023 reorganization (no Commercial Risk/Reinsurance/Health/Wealth segments remain). Revenue-by-solution-line slices ($11,290M + $5,907M = $17,197M) exceed reported total revenue ($17,181M) by $16M, likely rounding/minor intersegment items not separately broken out in the release. Operating-income-by-solution-line slices ($3,436M + $1,410M = $4,846M) exceed consolidated GAAP operating income ($4,344M) by $502M, which is exactly offset by unallocated corporate expenses/eliminations of -$502M disclosed in Aon's segment reconciliation table; no segment reported an operating loss. FY2021-2023 total revenue figures are sourced from Aon's prior-year 10-K filings as compiled by macrotrends.net (financial aggregator, cross-checked against Aon's historical press releases). Employee count (~60,000 as of Dec 31, 2025, unchanged from Dec 31, 2024) is per Aon's 10-K disclosure as compiled by stockanalysis.com. The '#2 global broker' ranking is a third-party estimate from Business Insurance's 2026 'World's 10 Largest Insurance Brokers' broker-profiles ranking (businessinsurance.com); Business Insurance did not publish a numeric market-share percentage in the available excerpt, so no percentage market-share figure is included -- only the clearly-attributed rank is reported. Adjusted (non-GAAP) operating income and adjusted EPS are company-disclosed non-GAAP measures, labeled as such.
